CC -!- FUNCTION: Secreted tyrosine phosphatase that plays a critical role
CC during infection as a bacterial effector protein that counteracts host
CC defenses. Required for intramacrophage survival.
CC {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
CC phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA-
CC COMP:10137, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474, ChEBI:CHEBI:46858,
CC ChEBI:CHEBI:82620; EC=3.1.3.48;
CC Evidence={ECO:0000250|UniProtKB:A0A0H3K9F2};
CC -!- SUBUNIT: Interacts with host CORO1A.
CC {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC Note=Secreted intracellularly upon bacterial infection of macrophages.
CC {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC -!- PTM: Phosophorylations at Tyr-122 and Tyr-123 are essential for
CC phosphatase activity. {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC -!- SIMILARITY: Belongs to the low molecular weight phosphotyrosine protein
CC phosphatase family. {ECO:0000305}.
